create python executable linux

Compile an executable. py file from the ground up in Python, Python is really powerful. But how powerful is he? Let's get to know it at. (It's good for me to take time to take a look at the tutorials when I come home from work every night ). Let's talk about the background: This is the case ~ In a studious spirit, I bought a book and learned the

Starting with Python 2.4, Python introduced the Subprocess module to manage sub-processes to replace some of the older modules ' methods:Os.system, Os.spawn, Os.popen, Popen2, commands.Not only can the external command be called as a child process, but it can also be connected to the Input/output/error pipeline of the child process to get the related return information.The subprocess package defines a numbe

The Python script file is packaged as an executable file for two purposes: A: You do not need to rely on the Python compiler to run the softwareTwo: Do not want to let their own source published Commonly used tools are: Py2exe, Cx_freeze, etc. "Tools: Py2exe" Installing Py2exeInstalling the tool is simple:Just download the installer for the version from the offi

Cx_freezeCx_freeze is a third-party library that can be used to package Python code into an executable file, and here's how to use a script file to turn Python code into an EXE executable file.First, you need to install the Cx_freeze, you can use the PIP to install, the installation method is as followsPip Install Cx_f

For dynamically linked executable programs, you need to load the linker ld first,Elf_entry = Load_elf_interp (...)The CPU control is given to the LD to load the dependent library, and the LD returns the CPU c

Python provides a description of the built-in functions for calling executable objects, involving exec, Eval, and compile three functions. The EXEC statement is used to execute a python statement stored in a code object, a string, a file, and the eval statement is used to calculate a valid python expression stored in a

body of the function (local), it is represented as a local static variable. In addition, if you add static to a function name, it means that it can only be called in the current file. Uninitialized data area (also called BSS area): The global uninitialized variable and the uninitialized static variable are deposited. Data in the uninitialized data area is initialized to 0 or empty (null) by the kernel before the program begins execution. For example, an uninitialized va

Long sum[1000]; The sum is stored in the uninitialized data area. Linux Process ArchitectureUnder a Linux system, if an executable is loaded into memory, it will becom

Make a linux executable program into a serviceWhen the linux system is started, we can see that many service programs are started one by one (that is, the lines with blue [OK ), these programs run in the background play an important role in using computers.

When the Linux system starts, we can see that many service programs are started one after another (that is, those with a blue [OK] in the back), these programs run in the background for us to use the computer played a very important role in this way to run the program has the following characteristics:Boot , shutdown, background runControl or view the running state of the corresponding program through the service commandWell, good, then how to make ou

First of all, if you have never touched the window before, you should first consider using Qt to create a simple ui. Here, we use the crawler s
